Description

Technical Field

[0001] The utility model relates to the technical field of motor magnetic shoes, in particular to a new type of magnetic shoe with different centers and the same diameter. Background Art

[0002] The eccentric same-diameter magnetic tile is a magnetic material with a unique structure composed of multiple eccentric annular magnets. Its working principle mainly involves the rearrangement of the magnetic moment of the magnetic material under the external magnetic field, which causes the magnetic tile itself to generate a magnetic field. By regulating the strength and direction of the external magnetic field, the magnetic strength and direction of the magnetic tile can be regulated, showing the characteristics of attraction and repulsion, which makes the magnetic tile widely used in electromagnetic equipment, magnetic sensors, magnetic fixtures and scientific experiments. For example, a new type of eccentric same-diameter magnetic tile disclosed in the authorization announcement number CN205921465U includes a first arc edge and a second arc edge connected to each other at both ends, the circumference radius of the first arc edge and the second arc edge is equal, the center of the first arc edge is the first center of the circle, the center of the second arc edge is the second center of the circle, the first center of the circle and the second center of the circle are on the same horizontal line and do not overlap, the magnetic tile is thick in the middle and thin at the two edges, the ratio of the circumference radius of the first arc edge to the second arc edge is 1:1, the center distance between the first center of the circle and the second center of the circle and the thickness of the magnetic tile is 1:1, and it consists of the first arc edge and the second arc edge. The composition has equal circumferential radii but non-coincidence centers, which reduces waste during wire cutting and reduces production costs. However, in this technical solution, the circumferential radii of the first arc edge and the second arc edge are equal, and only the centers do not coincide. However, the inner wall of the shell structure of some motor casings is not smooth. In order to ensure its own heat dissipation performance, the casing generally has heat dissipation ribs, fins, etc. on its inner wall, resulting in a number of equidistant vertical protrusions formed on the inner wall of the casing. The outer wall of the eccentric same-diameter magnetic tile is smooth, and it is difficult to fit with the vertical protrusions on the inner wall of the casing. This makes it difficult to effectively install and fix the magnetic tile in some compact spaces, thereby affecting the overall performance and stability of the motor. In addition, since the eccentric same-diameter magnetic tiles are difficult to fit with these protrusions, local gaps will appear at the installation position of the magnetic tiles, affecting the overall heat dissipation performance of the casing.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4 , the utility model provides an embodiment: a new type of eccentric and same-diameter magnetic tile, comprising an eccentric outer magnetic tile 1 and a concentric and equal-diameter inner magnetic tile 2 integrally formed on the outer wall of one side of the eccentric outer magnetic tile 1, a plurality of equidistant rectangular lower grooves 301 are arranged on the outer wall of the eccentric outer magnetic tile 1 away from the concentric and equal-diameter inner magnetic tile 2, a convex edge 302 is formed between two adjacent rectangular lower grooves 301, the rectangular lower grooves 301 and the convex edge 302 are at the same height as the eccentric outer magnetic tile 1 and the concentric and equal-diameter inner magnetic tile 2, the rectangular lower grooves 301 and the convex edge 302 form a ridge-type interlocking portion 3, by arranging the rectangular lower grooves 301 on the outer wall of the eccentric outer magnetic tile 1 and forming the convex edge 302, a tighter interlocking with the vertical protrusion structure on the inner wall of the casing can be achieved, so that the magnetic tile can better fit the inner wall of the casing;

[0018] The magnetic tile is interlocked with the protruding structure on the inner wall of the casing through the convex edge 302, and the interior of the rectangular lower groove 301 can be filled with glue, so that the eccentric outer magnetic tile 1 and the concentric equal-diameter inner magnetic tile 2 are fully bonded to the inner wall of the casing to maintain a stable connection. In a high-speed rotating motor, the possibility of the eccentric outer magnetic tile 1 and the concentric equal-diameter inner magnetic tile 2 falling off due to centrifugal force can also be effectively reduced;

[0019] The eccentric outer magnetic tile 1 is composed of a central arc edge 101 and side arc edges 102 at both ends of the central arc edge 101. The circumferential diameter of the central arc edge 101 is equal to the circumferential diameter of the concentric equal-diameter inner magnetic tile 2. The center of the central arc edge 101 and the center of the concentric equal-diameter inner magnetic tile 2 are on the same horizontal line and do not overlap. The circumferential diameter of the side arc edge 102 is smaller than the circumferential diameter of the central arc edge 101.

[0020] The thickness of the eccentric outer magnetic tile 1 is greater than that of the concentric equal-diameter inner magnetic tile 2. The eccentric outer magnetic tile 1 is located in the outer peripheral part of the motor, which can better guide and concentrate the magnetic field, thereby enhancing the overall magnetic flux density. At the same time, the concentric equal-diameter inner magnetic tile 2 is located in the inner peripheral part of the motor. Through reasonable design and layout, it can more effectively guide and distribute the magnetic field. This double-layer structure of magnetic tiles can make fuller use of the magnetic field and improve the magnetic effect of the motor. Moreover, since the magnetic tiles can better control and distribute the magnetic field, the magnetic field generated by the motor during operation changes less, reducing the vibration and noise of the motor and improving the stability of the motor.

[0021] A plurality of straight inner grooves 4 with equal spacing are arranged on the outer wall of the concentric equal-diameter inner magnetic tile 2 away from the eccentric outer magnetic tile 1;

[0022] Both ends of the eccentric outer magnetic tile 1 are provided with rounded chamfers. The eccentric outer magnetic tile 1 and the concentric equal-diameter inner magnetic tile 2 are both made of neodymium iron boron, which is a strong magnetic material with excellent magnetic permeability and magnetic saturation, and can therefore provide a stronger magnetic field. The outer surfaces of the eccentric outer magnetic tile 1 and the concentric equal-diameter inner magnetic tile 2 are nickel-plated. The outer surface nickel plating has excellent corrosion resistance. Motor equipment usually operates under various environmental conditions, including harsh conditions such as humidity and corrosive gases. By plating a nickel layer on the outer surface of the magnetic tile, the magnetic tile can be effectively prevented from corrosion and oxidation, thereby extending its service life while maintaining the stability of the magnetic properties.

[0023] When the embodiment of the present application is used, first, the eccentric same-diameter magnetic tile is integrally formed by the eccentric outer magnetic tile 1 and the concentric equal-diameter inner magnetic tile 2, and a plurality of equidistant downwardly extending rectangular lower grooves 301 are arranged on the outer wall of the eccentric outer magnetic tile 1 away from the concentric equal-diameter inner magnetic tile 2, that is, at the middle arc edge 101, and a convex edge 302 is formed between two adjacent rectangular lower grooves 301. By arranging the rectangular lower grooves 301 on the outer wall of the eccentric outer magnetic tile 1 and forming the convex edge 302, a tighter fit with the vertical protrusion structure on the inner wall of the casing can be achieved. , so that the magnetic tiles can better fit the inner wall of the casing, overcoming the problem that the original smooth magnetic tiles are difficult to fit, thereby improving the overall assembly efficiency and stability, and the setting of the rectangular lower groove 301 and the convex edge 302 not only helps to fit, but also can maintain the heat dissipation structure on the inner wall of the casing to a certain extent. By optimizing the shape and arrangement of the rectangular lower groove 301 and the convex edge 302, a good heat dissipation effect can be ensured. At the same time, the fit with the raised structure on the inner wall of the casing makes the heat dissipation surface smoother, further improving the heat dissipation performance.
